Mac OSX 10.9 resume folder copy to NAS

Question

I have a really big folder (174GB) that I wanted to move to a NAS using Ethernet. I started the transfer and when it was neary finished the computer stopped (I accidentally disabled caffeine) and the result on the NAS was this,it is recognized as a folder, and I can navigate into it with terminal, but unluckily cannot click on it to open.

I wanted to finish the copy, so I found This question which suggests to use curl with -O and -C options, but it does not apply to folders.

Is there a way to resume it (It took nearly a day and less than a GB is left), or at least to open it with finder?

Answer 1

You can use rsync to pick-up where you left off, in fact, with rsync's compression, you could have cut the transfer time down a bit. You will need to enable the Sharing --> Remote Login on the remote machine to be able to use rsync to/from it. When you enable Remote Login, the Sharing panel will display a message that says something like

To log in to this computer remotely, type "ssh whmcclos@192.168.0.2"

This will be the form of the rsync command you will use to copy/pick up where you left off:

$ rsync -avz source_folder whmcclos@192.168.0.2:path_relative_to_login_folder

So, I can put my ~/iTunes folder in my remote ~/Downloads folder, starting, or picking up where it left off with this command, assuming I'm sitting in my login folder:

$ rsync -avz iTunes whmcclos@192.168.0.2:Downloads

It will prompt for your remote password, construct a file list, and start or pick up transferring files. The -a switch means archive, and essentially gives you folder recursion. The -z switch uses compression in the network transfer. The -v switch displays what is happening during the transfer.

This should do the trick for you. There are many example in the rsync man page.
